Concrete with good workability and preparation method thereof
The invention provides concrete with good workability and a preparation method thereof, and belongs to the field of concrete. Raw materials of the concrete with good workability provided by the invention comprise a brand-new glue reducing agent, and the glue reducing agent is prepared from an alcohol amine compound, a quaternary ammonium salt surfactant, lignin or a derivative thereof, tannic acidand water. When the lignin derivative uses sulfonated lignin treated by horse radish peroxidase, the optimal effect is achieved. In addition, the glue reducing agent has better workability when beingused together with a naphthalene water reducing agent. The optimal initial slump of the concrete provided by the invention can reach 220mm.
本发明提供了一种和易性好的混凝土及其制备方法，属于混凝土领域。本发明提供的和易性好的混凝土的原料包括了一种全新的减胶剂，该减胶剂由醇胺类化合物、季铵盐类表面活性剂、木质素或其衍生物、单宁酸和水制备而成。当木质素衍生物使用辣根过氧化物酶处理过的磺化木质素时有最佳效果。此外，该类减胶剂与萘系减水剂共同使用时有更好的和易性。本发明提供的混凝土最佳初始坍落度可达220mm。
